研究了一种新型装配整体式住宅产业化结构构件,即装配整体式双向孔空心模板剪力墙的受剪性能。通过1个钢筋混凝土剪力墙和5个装配整体式双向孔空心模板剪力墙的拟静力试验,研究了其破坏模式和破坏过程,分析了内部接缝、轴压比、剪跨比、水平分布钢筋等参数对其受剪性能的影响。研究表明:装配整体式双向孔空心模板剪力墙的破坏过程和破坏模式与钢筋混凝土剪力墙不同,在水平荷载作用下沿内部接缝出现宏观竖向裂缝,经历整截面墙受力到分缝剪力墙受力的过程,避免了剪切破坏,具有良好的变形能力,但是受剪承载力降低;提高剪跨比,墙体承载力降低,承载力稳定性和变形能力提高;增加轴压比提高墙体的受剪承载力和抗侧刚度;提高水平钢筋配筋率提高墙体的受剪承载力和变形能力。
A new type of integral residential industrialized structural component is studied, that is, the shearing performance of a shear wall with an integral two-way hollow perforated formwork. Through the pseudo-static test of a reinforced concrete shear wall and five integral two-way hollow perforated shear walls, the failure mode and failure process are studied. The effects of internal joint, axial compression ratio, shear span ratio, Influence of Horizontal Distribution of Reinforcing Bar Parameters on Shear Performance. The research shows that the failure process and failure mode of the integral two-way hollow-core shear wall is different from that of reinforced concrete shear wall. Under the action of horizontal load, macroscopic vertical cracks appear along the inner joints, Shear wall shear force to avoid the process of shear damage, with good deformation capacity, but the shear capacity decreases; improve the shear span ratio, the wall bearing capacity decreases, bearing capacity stability and deformation capacity increase; increase the shaft Pressure ratio to improve the shear strength of the wall and the lateral stiffness; improve the level of reinforced reinforcement ratio to improve the wall shear capacity and deformation capacity.
